Science Simulations
Magnetic field created by electric current The magnetic field is the area surrounding a magnet in which the magnetic force exists. The magnetic field is also formed around the conductor through which the current flows. This … more
Electromagnetic induction Moving a magnet around a coil changes the magnetic field inside the coil, which causes current to flow through the coil. This phenomenon is called ‘electromagnetic induction’; the current flowing through the coil is … more
Build the indoor wiring to make the electric appliance work. Home wiring All electrical devices have a resistance value, and this resistor limits electric current. A power strip or indoor wiring is a parallel connection of … more
Electromagnetic induction Moving the magnet around the inductor will change the inductor’s magnetic field, which will cause the current to flow through the inductor. This phenomenon is called electromagnetic induction. The current flowing in the inductor … more
Resistance Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and … more
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the … more
Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate … more
Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. … more
Half Adder An adder is a logic circuit that can perform additional operations on binary numbers. It can be composed of only three types of logic circuits: AND, OR, and NOT gates. Bit addition is handled … more
Logic Gate Logic circuits are responsible for arithmetic operations in a computer. All numbers are converted to binary for the logic circuit to work. A binary number is a number system that consists only of the … more
Electric voltage(Regions of a positive or negative charge, such as those at the terminals of a battery) force electrons through a conductor. Electrons that have negative charges can be moved around a circuit. Originally, the current … more
When you rub a balloon on a cat, it charged. Charged balloons can be attached to walls or cat. The charged balloon rolls down as it discharges after a certain period of time. Triboelectricity If you … more
